I would LOVE to team up with a designer who knew their way around the Django template system. A little javascript/jquery/ajax experience would be nice, but I can always work that stuff in myself if someone who knows how to make something look good and flow cohesively tells me where they want it to go :)
You bring up an interesting point. How do you weigh Aesthetics/UX Flow/Front End Implementation? I think most folks look for the latter at the detriment of the former. BTW, If you are looking for designers shoot me an email. I have a lot of talented folks in my network who would love to talk to you!
I think any team consisting of 2-3 people can't afford any person who has only one skill.
It's a pretty common evolution for a designer to branch out into UX, so if one is looking for a designer it would be natural to look for a designer + UX engineer.
Personally I'd take designer+sales or designer+sysop pretty happily, but those are fairly rare skill blends!
I agree, I consider myself to be somewhat multifaceted and it would be nice to find a cofounder or two who could also help out with multiple aspects of the startup.
